Description

Technical Field

[0001] This utility model relates to the field of vehicles, and more specifically, to vehicle remote airbags. Background Technology

[0002] Remote airbags, as passive safety devices, are widely used in vehicles. In the event of a side collision, the remote airbag inflates and deploys between the driver and passengers, absorbing and dispersing the impact force from the driver's side, thereby effectively suppressing secondary collisions between the occupants.

[0003] These types of remote airbags typically include a main chamber connected to a gas generator and a head chamber connected to the main chamber via a single airway. The main chamber cushions the driver's torso impact, while the head chamber cushions the head impact. During a collision, gas is sequentially injected into the main chamber and the head chamber. Due to the single inflation path of the head chamber, there are issues with deployment delay and unstable deployment posture, resulting in less than ideal protective performance. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle remote airbag that deploys faster, deploys more stably, and has better safety protection performance.

[0005] The embodiments of this utility model provide a technical solution: A vehicle remote airbag includes an airbag body having a main chamber, a head chamber, and multiple connecting airways. The main chamber is in fluid communication with the head chamber through the multiple connecting airways. The main chamber is configured to cushion the torso impact of a driver or passenger after the airbag body is inflated and deployed. The head chamber is configured to cushion the head impact of a driver or passenger after the airbag body is inflated and deployed.

[0006] In an optional embodiment, the head chamber is located on one side of the main chamber in a first direction. When the air bag body is inflated and deployed, at least one of the connecting airways connects the main chamber and the head chamber on the same side in a second direction, where the first direction and the second direction form an angle.

[0007] In an optional embodiment, the head chamber is located on one side of the main chamber in a first direction, and in the inflated and deployed state of the air bag body, at least one of the connecting airways connects the main chamber and the head chamber on the two sides that are close to each other in the first direction.

[0008] In an optional embodiment, the airbag body includes a first piece and a second piece. The first piece includes a first sheet and a second sheet that are folded together. The first sheet and the second piece are sewn together to form the main chamber, and the second sheet and the second piece are sewn together to form the head chamber.

[0009] In an optional embodiment, the first piece further includes a folded portion connecting the first piece and the second piece, the folded portion being sewn together with the second piece to form at least one of the connecting airways.

[0010] In an optional embodiment, the first piece has a through hole in the overlapping area of ​​the first piece and the second piece, and the first piece and the second piece are sewn together along the periphery of the through hole to form a connecting airway.

[0011] In an optional embodiment, the airbag body further includes a third panel sewn together to form a support chamber in fluid communication with the main chamber.

[0012] In an optional embodiment, the vehicle remote airbag further includes an inner traction strap disposed within the main chamber. When the airbag body is inflated and deployed, the inner traction strap is located in the middle region of the main chamber in the vertical direction, and is configured to limit the thickness dimension of the main chamber in a first direction.

[0013] In an optional embodiment, the vehicle remote airbag further includes a first external strap, wherein when the airbag body is inflated and deployed, one side of the head chamber in a second direction is connected to one end of the first external strap, and the other end of the first external strap is configured to connect to the main chamber or the vehicle seat.

[0014] In an optional embodiment, the vehicle remote airbag further includes a second outer strap, wherein when the airbag body is inflated and deployed, the head chamber is connected to one end of the second outer strap in the middle region in a second direction, and the other end of the second outer strap is configured to connect to the main chamber or the vehicle seat.

[0015] In an optional embodiment, the airbag body further has a support chamber communicating with the main chamber, wherein when the airbag body is inflated and deployed, the support chamber and the head chamber are respectively located on both sides of the main chamber in a first direction.

[0016] In an optional embodiment, the support chamber is located above or below the main chamber.

[0017] In an optional embodiment, when the airbag body is inflated and deployed, the projection of the support chamber in the first direction is circular, elliptical, or polygonal.

[0018] Compared to existing technologies, the vehicle remote airbag provided by this invention has a main chamber and a head chamber that are fluidly connected via multiple connecting airways. Upon impact, gas from the main chamber can inflate the head chamber through these connecting airways. This significantly improves the deployment speed of the head chamber and enhances the uniformity of inflation in different areas of the head chamber, allowing the head chamber to deploy in a more stable posture and form a stable and reliable position in a very short time, thus protecting the driver's head. Therefore, the beneficial effects of the vehicle remote airbag provided by this invention include: faster deployment speed, more stable deployment posture, and better safety protection performance.

[0028] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] First Embodiment Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of the vehicle remote airbag 100 provided in this embodiment in practical application.

[0030] The vehicle remote airbag 100 provided in this embodiment includes an airbag body 110 that can be deployed after inflation. In practical applications, the airbag body 110 is stored in a folded or rolled-up state within the left side panel of the driver's seat 200 and connected to a gas generator. When the vehicle experiences a collision of a certain magnitude, the gas generator is activated, and a large amount of gas is instantly generated through a chemical reaction, filling the airbag body 110. This causes the airbag body 110 to rapidly deploy between the driver's seat 200 and the passenger seat, forming a cushioning airbag structure to achieve a protective effect against lateral impacts to the occupants.

[0031] Please refer to the following: Figure 2 , Figure 3 and Figure 4 , Figure 2 The image shown is a schematic diagram of the vehicle remote airbag 100 provided in this embodiment from one perspective. Figure 3 The image shown is a schematic diagram of the vehicle's remote airbag 100 from another perspective. Figure 4 The diagram shown is a structural schematic of the vehicle's remote airbag 100 from another perspective.

[0032] The airbag body 110 has a main chamber 120, a head chamber 130 and a support chamber 180. When the airbag body 110 is inflated and deployed, the head chamber 130 and the support chamber 180 are located on both sides of the main chamber 120 in the first direction and are in fluid communication with the main chamber 120.

[0033] In fact, the main chamber 120 is configured to cushion the torso impact of the occupants after the airbag body 110 is inflated and deployed, the head chamber 130 is configured to cushion the head impact of the occupants after the airbag body 110 is inflated and deployed, and the support chamber 180 is configured to abut against the vehicle armrest box 300 or the passenger seat after the airbag body 110 is inflated and deployed, so as to provide support for the main chamber 120.

[0034] Specifically, in this embodiment, the head chamber 130 is located in the upper right region of the main chamber 120, and the support chamber 180 is located in the lower left region of the main chamber 120.

[0035] Figure 2 The direction indicated by the X arrow is the first direction; the direction indicated by the Z arrow is the vertical direction, that is, the height direction of the vehicle. Figure 3 The direction indicated by the Y-arrow is the second direction. It can be understood that the first direction in this embodiment refers to the left and right direction of the vehicle. The head chamber 130 is located to the right of the main chamber 120, that is, the side closer to the driver's seat 200; the support chamber 180 is located to the left of the main chamber 120, that is, the side closer to the passenger seat. The orientation descriptions in this embodiment are all based on the state of the airbag body 110 being deployed.

[0036] After the airbag body 110 deploys following a vehicle collision, as the driver moves laterally to the left, the main chamber 120 supports the driver's torso, thus cushioning the impact. The head chamber 130, positioned above the driver's left shoulder, supports the driver's head, thus cushioning the impact. The support chamber 180 abuts against the armrest 300 and / or the passenger seat, providing strong support to the main chamber 120 and preventing excessive lateral swaying or vertical collapse, thereby achieving better protection.

[0037] Understandably, in the event of a vehicle collision, the head chamber 130 needs to fully and uniformly deploy within a very short time to provide stable and reliable cushioning for the driver's head. To improve the deployment speed of the head chamber 130 and optimize its deployment posture, in this embodiment, the airbag body 110 also has multiple connecting airways 140, and the main chamber 120 is fluidly connected to the head chamber 130 through the multiple connecting airways 140.

[0038] During the deployment of the airbag body 110, the gas in the main chamber 120 can be injected into the head chamber 130 through multiple connecting air channels 140, causing the head chamber 130 to deploy rapidly. Furthermore, air enters from multiple locations in the head chamber 130 simultaneously, improving the uniformity of air intake in different parts of the head chamber 130 and ensuring that the head chamber 130 can deploy in a stable posture.

[0039] Please refer to the above. Figure 5 and Figure 6 , Figure 5 The image shown is a perspective view of a vehicle remote airbag 100. Figure 6 The diagram shows the connection structure between the main chamber 120 and the head chamber 130.

[0040] Specifically, in this embodiment, there are two connecting airways 140. When the air bag body 110 is inflated and deployed, one connecting airway 140 connects the rear side of the main chamber 120 to the rear side of the head chamber 130, and the other connecting airway 140 connects the right side of the main chamber 120 to the left side of the head chamber 130.

[0041] It is understood that in this embodiment, the head chamber 130 is located to the right of the main chamber 120, and the head chamber 130 has a certain amount of expansion in both the front-back and left-right directions. During the inflation and deployment of the air bag body 110, a portion of the gas in the main chamber 120 is injected into the rear of the head chamber 130 through the connecting air passage 140 on its rear side, causing the head chamber 130 to expand rapidly in the front-back direction; at the same time, another portion of the gas in the main chamber 120 is injected into the left side of the head chamber 130 through the connecting air passage 140 on its right side, causing the head chamber 130 to expand rapidly in the left-right direction.

[0042] Furthermore, when the airflows from the two connecting airways 140 enter the head chamber 130 simultaneously, the two airflows will generate turbulent disturbances and momentum collisions within the head chamber 130, which can quickly disperse the airflow and promote the rapid and uniform distribution of gas within the head chamber 130. This ensures that the gas volume in each area of ​​the head chamber 130 is uniform and avoids local over-expansion and hardening or local insufficient gas volume and collapse.

[0043] As can be seen, by simultaneously introducing air through the two connecting airways 140 located on the rear and left sides of the head chamber 130, the deployment speed of the head chamber 130 is increased, while the deployment posture of the head chamber 130 is kept stable, thus significantly improving the buffering effect of the head chamber 130 on head impact.

[0044] In another embodiment, a greater number of connecting airways 140 may be configured in the airbag body 110 according to actual application conditions. For example, the rear side of the main chamber 120 may be connected to the rear side of the head chamber 130 through a greater number of connecting airways 140, and the right side of the main chamber 120 may also be connected to the left side of the head chamber 130 through a greater number of connecting airways 140.

[0045] It should be noted that the location of the connecting airway 140 is not limited to the left and rear sides of the head chamber 130. For example, in another embodiment, at least one of the plurality of connecting airways 140 on the air bag body 110 can communicate the top of the main chamber 120 with the top of the head chamber 130.

[0046] The vehicle remote airbag 100 provided in this embodiment has an airbag body 110 formed by sewing together three pieces of fabric. The three pieces are a first piece 111, a second piece 112, and a third piece 113. The first piece 111 and the second piece 112 are sewn together to form a main chamber 120, a head chamber 130, and a rear connecting airway 140. The third piece 113 is sewn together to form a support chamber 180 and is sewn together with the second piece 112 to form an airway connecting the main chamber 120 and the support chamber 180.

[0047] In fact, the first piece 111 needs to be folded and sewn before it can be sewn together with the second piece 112. Please refer to the relevant documentation. Figure 7 and Figure 8 , Figure 7 The diagram shown is a structural schematic of the first piece 111 before folding and sewing. Figure 8 The diagram shows the structure of the first piece 111 after folding and sewing.

[0048] In this embodiment, the first piece 111 includes a first sheet 1111, a second sheet 1112, and a folding portion 1113 connecting the first sheet 1111 and the second sheet 1112. The first sheet 1111 and the second sheet 1112 are folded together at the folding portion 1113. The edges of the first sheet 1111 and the second piece 112 are sewn together to form a main chamber 120, and the edges of the second sheet 1112 are sewn together to form a head chamber 130.

[0049] Please refer to the following: Figure 9 and Figure 10 , Figure 9 The diagram shown is a structural schematic of the second cut piece 112. Figure 10 The diagram shows a partial sewing of the second piece 112 and the first piece 111.

[0050] In this embodiment, the second piece 112 has the same edge shape as the first piece 111. The second piece 112 also has a third piece 1121 with the same edge shape as the first piece 1111, a fourth piece 1122 with the same edge shape as the second piece 1112, and a connecting portion 1123 connecting the third piece 1121 and the fourth piece 1122.

[0051] When the second piece 112 is edge-stitched with the first piece 111, the two parts of the second piece 112 are folded in accordance with the folding structure of the first piece 111. That is, the third piece 1121 is edge-stitched with the first piece 1111 to form the main chamber 120, the fourth piece 1122 is edge-stitched with the second piece 1112 to form the head chamber 130, and the connecting part 1123 is edge-stitched with the folding part 1113 to form the connecting airway 140 connecting the main chamber 120 and the rear side of the head chamber 130.

[0052] As for the connecting airway 140 connecting the right side of the main chamber 120 and the left side of the head chamber 130, it is formed by folding and sewing the first piece 111 itself. Specifically, the first piece 111 has an opening 1114 through the overlapping area of ​​the first piece 1111 and the second piece 1112, and the first piece 1111 and the second piece 1112 are sewn along the periphery of the opening 1114 to form the connecting airway 140.

[0053] In fact, both the first piece 1111 and the second piece 1112 of the first cut piece 111 have through holes 1114. When the first piece 1111 and the second piece 1112 are folded together with the folding part 1113, the holes 1114 on the first piece 1111 and the second piece 1112 are aligned. In this state, by sewing the edges of the holes 1114, a connecting airway 140 connecting the right side of the main chamber 120 and the left side of the head chamber 130 can be obtained.

[0054] As can be seen, in this embodiment, the main chamber 120, the head chamber 130, and all connecting airways 140 connecting the main chamber 120 and the head chamber 130 are formed by sewing together the first piece 111 and the second piece 112, eliminating the need for additional sheets, reducing material costs and providing better structural integrity.

[0055] Please refer to the following: Figure 11 and Figure 12 , Figure 11 The diagram shown is a structural schematic of the third piece 113. Figure 12 The diagram shows the structure of the sewing connection between the third piece 113 and the second piece 112.

[0056] In this embodiment, the third piece 113 has a T-shaped structure, with an air vent 114 penetrating through its middle portion. Similarly, the lower region of the third piece 1121 of the second piece 112 also has a corresponding air vent 114 penetrating through it. After sewing the second piece 112 to the first piece 111, the air vent 114 on the third piece 113 is aligned with the air vent 114 on the second piece 112, and the third piece 113 is sewn to the second piece 112 along the edge of the air vent 114, thereby forming an air passage connecting the main chamber 120 and the support chamber 180.

[0057] Please refer to the following: Figure 13 , Figure 13 The diagram shows a structural schematic of the third piece 113 sewn together to form the supporting chamber 180.

[0058] After completing the sewing connection between the third piece 113 and the second piece 112, the T-shaped structure of the third piece 113 is folded to obtain a roughly rectangular folded structure. The edges of the folded structure are then sewn together to obtain the roughly rectangular support chamber 180 in the unfolded state.

[0059] As can be seen, when the airbag body 110 is inflated and deployed, the projection of the support chamber 180 in this embodiment in the left-right direction is approximately rectangular. The support chamber 180 has a bottom wall surface that can stably support the armrest box 300 and a left wall surface that can stably support the passenger seat, making the state of the support chamber 180 stable, thereby providing a stable and reliable support effect for the main chamber 120 and further improving the protective performance of the airbag.

[0060] Please refer to the following: Figure 14 and Figure 15 , Figure 14 The diagram shown is a structural schematic of the vehicle remote airbag 100 provided in this embodiment, when equipped with an inner traction strap 150. Figure 15 As shown Figure 14 The structural block diagram of the vehicle remote airbag 100.

[0061] like Figure 14 As shown, in practical applications, an inner pull strap 150 can also be provided inside the main chamber 120 to increase its internal pressure and further improve stability. When the air bag body 110 is inflated and deployed, the inner pull strap 150 is configured in the middle area of ​​the main chamber 120 in the vertical direction to limit the thickness of the main chamber 120 in the left and right directions.

[0062] Specifically, the two ends of the inner pull strap 150 are respectively connected to the first piece 1111 of the first piece 111 and the third piece 1121 of the second piece 112 to limit the distance between the first piece 1111 and the third piece 1121 in the left and right directions when the main chamber 120 is unfolded, so that the left and right sides of the middle area of ​​the main chamber 120 in the vertical direction are recessed, thereby reducing the volume of the main chamber 120 and increasing the internal pressure of the main chamber 120 to provide better restraint and support for the driver's torso.

[0063] Please refer to the following: Figure 16 and Figure 17 , Figure 16 The diagram shown is a structural schematic of the vehicle remote airbag 100 provided in this embodiment when it is equipped with a first external traction strap 160. Figure 17 As shown Figure 16 A perspective view of the vehicle remote airbag 100 shown.

[0064] like Figure 16 As shown, in practical applications, a first external strap 160 can also be connected to the front side of the head chamber 130. When the air bag body 110 is inflated and deployed, the front side of the head chamber 130 is connected to one end of the first external strap 160, and the other end of the first external strap 160 is configured to connect to the vehicle seat.

[0065] During the inflation and deployment of the airbag body 110, the first outer pull strap 160 constrains the deployment direction of the head chamber 130. After the airbag body 110 is deployed, the first outer pull strap 160 provides a pulling force to the front of the head chamber 130, maintaining the stability of the head chamber 130 and the main chamber 120, thereby enhancing the buffer protection capability of the head chamber 130 and the main chamber 120 for the driver.

[0066] Please refer to the following: Figure 18 and Figure 19 , Figure 18 The diagram shown is a structural schematic of the vehicle remote airbag 100 provided in this embodiment, which is equipped with a first external traction strap 160 and a second external traction strap 170. Figure 19 As shown Figure 18 A perspective view of the vehicle remote airbag 100 shown.

[0067] like Figure 18As shown, in practical applications, a first external strap 160 can be connected to the front of the head chamber 130, and a second external strap 170 can be arranged in the middle of the head chamber 130. Similarly, when the airbag body 110 is inflated and deployed, the front of the head chamber 130 is connected to one end of the first external strap 160, and the other end of the first external strap 160 is configured to connect to the vehicle seat. The middle area of ​​the head chamber 130 in the front-rear direction is connected to one end of the second external strap 170, and the other end of the second external strap 170 is also configured to connect to the vehicle seat.

[0068] During the inflation and deployment of the airbag body 110, the first outer pull strap 160 and the second outer pull strap 170 jointly constrain the deployment direction of the head chamber 130. After the airbag body 110 is deployed, the first outer pull strap 160 provides a pulling force to the front of the head chamber 130, and the second outer pull strap 170 provides a pulling force to the middle position of the head chamber 130, maintaining the stability of the head chamber 130 and the main chamber 120, and obtaining better cushioning and protection capabilities.

[0069] Second Embodiment Please see Figure 20 , Figure 20 The diagram shown is a structural schematic of the vehicle remote airbag 100 provided in this embodiment.

[0070] The difference between the vehicle remote airbag 100 provided in this embodiment and the first embodiment lies in the location of the support chamber 180. In the first embodiment, the support chamber 180 is located in the lower left region of the main chamber 120, while in this embodiment, the support chamber 180 is located in the upper left region of the main chamber 120.

[0071] Since the head chamber 130 is located in the upper right region of the main chamber 120, while in this embodiment the support chamber 180 is located in the upper left region of the main chamber 120, the support chamber 180 is closer to the head chamber 130 in the vertical direction.

[0072] Therefore, in the event of a vehicle collision, under the lateral impact on the driver, the support chamber 180 rests against the passenger seat and can provide reliable lateral support to the head chamber 130 through the main chamber 120, preventing the upper area of ​​the main chamber 120 from swinging significantly relative to the lower area, thereby avoiding neck sprains for the driver.

[0073] The vehicle remote airbag 100 provided in this embodiment is also formed by sewing together the first piece 111, the second piece 112 and the third piece 113. The structure and sewing method of the first piece 111, the second piece 112 and the third piece 113 are basically the same as those in the first embodiment. The difference is that the opening position of the air hole 114 on the second piece 112 is different.

[0074] Please refer to the following: Figure 21 , Figure 22 and Figure 23 , Figure 21 The diagram shown is a structural schematic of the second cut piece 112 in this embodiment. Figure 22 The diagram shown is a structural schematic of the sewing connection between the third piece 113 and the second piece 112 in this embodiment. Figure 23 The diagram shown is a structural schematic of the support chamber 180 formed by sewing the third piece 113 in this embodiment.

[0075] In this embodiment, the air passage 114 on the second piece 112 is disposed through the upper region of the third piece 1121. After aligning the air passage 114 on the third piece 113 with the air passage 114 on the second piece 112 and sewing the edges together, an air passage is formed that connects the upper region of the support chamber 180 and the main chamber 120.

[0076] like Figure 23 As shown, in this embodiment, the support chamber 180 is also roughly rectangular in shape. That is, when the air bag body 110 is inflated and unfolded, the projection of the support chamber 180 in the left and right directions is roughly rectangular, which is consistent with the support chamber 180 in the first embodiment.

[0077] In another embodiment, the shape of the support chamber 180 can also be adjusted according to actual application conditions, and is not limited to the approximately cuboid structure in this embodiment and the first embodiment. When the air bag body 110 is inflated and deployed, the projection of the support chamber 180 in the left-right direction can be circular, elliptical, or other polygonal.

[0078] Please refer to the following: Figure 24 and Figure 25 , Figure 24 The diagram shown is a schematic representation of a vehicle distal airbag 100 with a generally spherical support chamber 180, provided in another embodiment. Figure 25 As shown Figure 24 A perspective view of a vehicle remote airbag 100.

[0079] like Figure 24 As shown, the support chamber 180 is roughly spherical, meaning that when the air bag body 110 is inflated and deployed, the projection of the support chamber 180 in the left-right direction is roughly circular.

[0080] Compared to the rectangular support chamber 180, the spherical support chamber 180 has less stress concentration, more uniform structural stress, and more complete unfolding, with a more stable and controllable unfolding posture.

[0081] Furthermore, in this embodiment, an inner pull strap 150 is also provided inside the main chamber 120. The inner pull strap 150 is in the middle area of ​​the main chamber 120 in the vertical direction when the air bag body 110 is inflated and unfolded, so as to limit the thickness of the main chamber 120 in the left and right direction.

[0082] Please refer to the following: Figure 26 and Figure 27 , Figure 26 The diagram shown is a schematic representation of a vehicle distal airbag 100 with a generally ellipsoidal supporting chamber 180, provided in another embodiment. Figure 27 As shown Figure 26 A perspective view of a vehicle remote airbag 100.

[0083] like Figure 26 As shown, the support chamber 180 is approximately ellipsoidal, meaning that when the air bag body 110 is inflated and deployed, the projection of the support chamber 180 in the left-right direction is approximately elliptical.

[0084] Compared to the cuboid-shaped support chamber 180, the ellipsoidal support chamber 180 also features more uniform force distribution, more complete expansion, and a more stable and controllable expansion posture. Furthermore, compared to the spherical support chamber 180, the ellipsoidal support chamber 180 can achieve a larger expansion dimension in the left-right, front-back, or up-down directions, resulting in better support stability. In this embodiment, the main chamber 120 is also equipped with an inner pull strap 150.

[0085] It should be noted that, in practical applications, a first external traction strap 160 and a second external traction strap 170 can also be configured for the head chamber 130 of the vehicle remote airbag provided in the second embodiment to further improve the stability of the main chamber 120 and the head chamber 130.

[0086] Please refer to the following: Figure 28 and Figure 29 , Figure 28 The diagram shown is a structural schematic of the vehicle remote airbag 100 provided in this embodiment when it is equipped with a first external traction strap 160. Figure 29 As shown Figure 28 A perspective view of the vehicle remote airbag 100 shown.

[0087] Similarly, the vehicle remote airbag 100 provided in this embodiment can also be connected to the front side of its head chamber 130 with a first external strap 160. When the airbag body 110 is inflated and deployed, the front side of the head chamber 130 is connected to one end of the first external strap 160, and the other end of the first external strap 160 is configured to connect to the vehicle seat.

[0088] During the inflation and deployment of the airbag body 110, the first outer pull strap 160 constrains the deployment direction of the head chamber 130. After the airbag body 110 is deployed, the first outer pull strap 160 provides a pulling force to the front of the head chamber 130, maintaining the stability of the head chamber 130 and the main chamber 120, thereby enhancing the buffer protection capability of the head chamber 130 and the main chamber 120 for the driver.

[0089] Please refer to the following: Figure 30 and Figure 31 , Figure 30 The diagram shown is a structural schematic of the vehicle remote airbag 100 provided in this embodiment, which is equipped with a first external traction strap 160 and a second external traction strap 170. Figure 31 As shown Figure 30 A perspective view of a vehicle remote airbag 100.

[0090] Similarly, the vehicle remote airbag 100 provided in this embodiment can also have a first external strap 160 connected to the front side of its head chamber 130, and a second external strap 170 arranged in the middle of the head chamber 130. Likewise, when the airbag body 110 is inflated and deployed, the front side of the head chamber 130 is connected to one end of the first external strap 160, and the other end of the first external strap 160 is configured to connect to the vehicle seat. The middle area of ​​the head chamber 130 in the front-rear direction is connected to one end of the second external strap 170, and the other end of the second external strap 170 is also configured to connect to the vehicle seat.

[0091] During the inflation and deployment of the airbag body 110, the first outer pull strap 160 and the second outer pull strap 170 jointly constrain the deployment direction of the head chamber 130. After the airbag body 110 is deployed, the first outer pull strap 160 provides a pulling force to the front of the head chamber 130, and the second outer pull strap 170 provides a pulling force to the middle position of the head chamber 130, maintaining the stability of the head chamber 130 and the main chamber 120, and obtaining better cushioning and protection capabilities.

[0092] In summary, the vehicle remote airbag 100 provided in this application has the characteristics of faster deployment speed and more stable deployment posture, and its safety protection performance is more stable and reliable.

[0093] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
